おかげで means thanks to, because of, or owing to in a positive sense.

So 修理受付番号のおかげで means thanks to the repair reception number / because I had the repair reference number.

A key nuance:

• おかげで usually sounds appreciative or favorable.
• It suggests that something helpful made the good result possible.

So this is not just neutral cause-and-effect; it has a mild feeling of gratitude or benefit.

Because おかげ is a noun.

When one noun modifies another noun in Japanese, you often use の.

So:

• 修理受付番号 = repair reference number
• 修理受付番号のおかげで = thanks to the repair reference number

This pattern is very common:

• 友だちのおかげで = thanks to my friend
• 先生のおかげで = thanks to the teacher

You can also use a whole clause before おかげで:

• 手伝ってくれたおかげで = thanks to you helping me

It is a noun compound, which is very common in Japanese.

You can break it down like this:

• 修理 = repair
• 受付 = reception, acceptance, intake
• 番号 = number

Together, 修理受付番号 means something like:

• repair reception number
• repair request number
• repair reference number
• service ticket number

Japanese often stacks nouns together like this without extra words such as for, of, or request.

Because the verb is 分かる, not 分ける or 理解する.

分かる is usually treated as an intransitive verb, and the thing that becomes understood is marked with が.

So:

• 進捗状況が分かりました = the progress status became clear / I understood the progress status

This can feel strange to English speakers, because English uses a direct object:

• I understood the progress

But in Japanese, the structure is closer to:

• The progress status became understandable / became clear to me

That is why が is natural here.

Here, 分かりました means something like:

• I found out
• I understood
• I was able to tell
• it became clear

In this sentence, it probably means:

• I could quickly tell the current status
• I quickly found out the progress

It does not sound like deep academic understanding. It sounds more like getting clear information.

Japanese often uses the past tense when talking about a completed realization.

So 分かりました does not always mean only understood in the past in a strict timeline sense. It often means:

• I came to understand
• I found out
• I was able to see

Here, the idea is that after using the repair reference number, the speaker was able to check the status, and that result happened successfully.

If you said 分かります, it would sound more like:

• I can tell
• I understand
• a more general or non-completed statement

すぐ means:

• immediately
• right away
• quickly

Here it modifies 分かりました.

So:

• 進捗状況がすぐ分かりました = I quickly found out the progress status / the progress status became clear right away

The point is that the repair reference number made it easy to know the status without delay.

Because Japanese often omits subjects when they are obvious from context.

Even though English would often say:

• I quickly found out the progress status

Japanese does not need to say 私は unless there is a reason to emphasize the speaker or contrast them with someone else.

So this sentence naturally focuses on:

• the helpful thing: 修理受付番号
• the result: 進捗状況がすぐ分かりました

rather than explicitly naming the subject.

進捗状況 means progress status or current progress.

Breakdown:

• 進捗 = progress, especially progress of work or a process
• 状況 = condition, state, situation, status

So 進捗状況 is a somewhat formal expression meaning:

• the status of the progress
• how far things have progressed

Yes, sometimes just 進捗 is enough. But 進捗状況 sounds a little more explicit and businesslike, which fits a repair or customer-service context well.

Yes, but the nuance changes.

Compare:

• 修理受付番号で、進捗状況がすぐ分かりました。

  • Using the repair reference number, I could quickly tell the status.
  • More neutral; focuses on the means/tool.

• 修理受付番号のおかげで、進捗状況がすぐ分かりました。

  • Thanks to the repair reference number, I could quickly tell the status.
  • More appreciative; emphasizes the benefit.

So で shows method or means, while おかげで adds a feeling of helpfulness or gratitude.

It is polite but not extremely formal.

The politeness comes from 分かりました, which is the -ます form in the past tense.

So it is suitable for:

• everyday polite conversation
• customer service situations
• business communication

A casual version would be:

• 修理受付番号のおかげで、進捗状況がすぐ分かった。

That would sound plain and less polite.

No, normal Japanese writing usually does not use spaces between words.

This sentence would normally be written like this:

修理受付番号のおかげで、進捗状況がすぐ分かりました。

The spaces were probably added for learners to make the structure easier to see.

So for study purposes, the spaced version is helpful, but in real Japanese text, you should expect no spaces.
